New medical instruments for sports medicine and orthopaedic surgery

UNESCO defines sports as physical activity that promotes health (2015). Indeed, it is well established that sports reduces the number of deaths caused by non-communicable disease, which Lancet estimates accounts for 68% globally (2012). Overall, sports are good for health and lifespan, and will have high impact on societies.

With this point in mind, a lot of biomechanical research has been performed on bone, cartilage, ligaments and tendons. Further, progressing in minimal invasive surgery such as arthroscopic surgery, sports medical biomechanics is commanding attention as academic research for therapy that promotes health recovery, benefitting athletes and sports enthusiasts.

We are working with industry for innovative orthopedic surgery and sports medicine. Examples include development of new arthroscopic instruments for regenerative medicine with Smith and Nephew, Japan, and establishment of evaluation for dynamic balance and new training methods of balance with Protea Japan. Further, we are biomechanically researching the effect of surgery and general exercise on the outcomes after arthroscopic surgeries with the purpose of applying it to general society.
